## com.epochx.action
Class Action

    java.lang.Object
      com.epochx.action.Action

Direct Known Subclasses:
  AntAction

    public abstract class Action

extends java.lang.Object

Actions provide a system for performing events or actions that have side-effects rather than returning a literal value. For problems such as the artificial ant, instead of `CandidatePrograms` being defined as having a return type of boolean or double, they have a return type of Action. As such different Action 'values' are used. The model will define `TerminalsNodes` with values that are Action objects such as `AntMoveAction`or `AntTurnLeftAction`.``

When these TerminalNodes are evaluated, their action values get executed - which may result in an artificial ant moving across an artificial landscape. But all evaluations must return a result, and since the TYPE of these Nodes is Action, they return Action.DO_NOTHING which indicates that no further execution is required, and if executed will do nothing.

Field Summary
`static Action` | `DO_NOTHING` This predefined Action object should be used when no action should be performed.

Constructor Summary
`Action()`

Method Summary
`abstract void` | `execute()` The execute method should be called to perform whatever action this `Action` represents.
